    Thank you Seetharaman.

    Jacques Rotenberg points out that he sent a similar problem for my Jubilee Tourney. I now regret not including it in my award despite it being such a clear and striking demo of Superguards. Luckily for Bala Jacuqes failed to publish it elsewhere.

    Sorry Mr. Jacques Rotenberg that your problem did not figure in the award for which I feel you really deserve. Since it was your original idea (though I was unaware of it), if you agree can I ask Ms. Julia to add your name also for the above published problem?

    The set play is 1…Kc6 2.Ka6 a8=R/Q#

    Dear Jacques,
    Thanks for pointing out the set play which completes AUW.

    The dual mate a8R/Q# is exactly opposite to the essence of AUW.

    Thank Nikola. Yes, I agree that AUW cannot be claimed for this setting. It is purely two under promotion problem.
