' What have you done yet again, why, O Yudhishthira! is it not plain?

You gave Duryodhana choice of weapon and whom to fight!

A chance to win back the kingdom ... did millions die for you  in vain?

You still gamble - have you lost both hind and foresight ?

Why the Pandava birthright once again you place at stake?'

Thus admonished Krishna astonished at Dharma's mistake

Hearing venomous Duryodhana hiss vengeful as a wounded snake

Evil re-emerging gleeful  from the deep Dwaipayana lake

Reassuring Vasudeva, Bhima to the occasion rose

To battle - the duo dealing each with deadly blows

Dharma against adharma sometimes hies, but also it lows

Vows of the warriors - be it fair or foul -play too close!

When Krishna said  maya by maya fight

At the start did Yudhisthira hear Him right?

When Krishna said deva by kriya did asura blight

Mahabharat of Vyasa reveals many an insight!

references:

"Sanjaya said, 'Whilst Duryodhana, O king, was repeatedly roaring in this strain, Vasudeva, filled with wrath, said these words unto Yudhishthira, "What rash words hast thou spoken, O king, to the effect, 'Slaying one amongst us be thou king among the Kurus.' If, indeed, O Yudhishthira, Duryodhana select thee for battle, or Arjuna, or Nakula, or Sahadeva (what will be the consequence)? From desire of slaying Bhimasena, O king, for these thirteen years hath Duryodhana practised with the mace upon a statue of iron! How then, O bull of Bharata's race, will our purpose be achieved? From compassion, O best of kings, thou hast acted with great rashness! I do not at this moment behold a match (for Duryodhana) except Pritha's son Vrikodara! His practice, again, with the mace, is not so great! Thou hast, therefore, once more allowed a wretched game of chance to commence as that one in former days between thyself and Shakuni, O monarch! Bhima is possessed of might and prowess. King Suyodhana, however, is possessed of skill! In a contest between might and skill, he that is possessed of skill, O king, always prevails! Such a foe, O king, thou hast, by thy words, placed in a position of ease and comfort! Thou hast placed thine own self, however, in a position of difficulty. We have, in consequence of this, been placed in great danger! Who is there that would abandon sovereignty within grasp, after having vanquished all his foes and when he hath only one foe to dispose of and that one plunged in difficulties? I do not see that man in the world today, be he a god, who is competent to vanquish the mace- armed Duryodhana in battle! Neither thou nor Bhima, nor Nakula nor Sahadeva, nor Phalguna, is capable of vanquishing Duryodhana in fair fight! King Duryodhana is possessed of great skill! How then, O Bharata, canst thou say unto such a foe words such as these, 'Fight, selecting the mace as thy weapon, and if thou canst slay one amongst us, thou shalt then be king?' If Duryodhana encounters Vrikodara amongst us wishing to fight fairly with him, even then our victory would be doubtful. Duryodhana is possessed of great might and great skill. How couldst thou say unto him, 'Slaying only one amongst us be thou king'? " [MB/KMG/Shalya Parva/Chap.33]evaṃ duryodhano rājan garjamāne muhur muhuḥ
