WinTD Pairings

OK, I once ran an event or two (u.s. masters) with NTD Vs WinTD Vs SwissSys pairings. The conclusion I came to was that those pairings were all legal.

Mr. Just, glad you I would wonder if SwissSys would pair our tournament the same as WinTD did? George Mirijanian, thought that the pairings for rd 3 were not correct on how WinTD had made the pairings, giving 7 vs 4. George Mirijanian thought that it was correct to change to 4 vs 7.

Umm…I made no comment on “best” Vs legal. My observation is that Legal is not the same as Best in the long run

So to conclude WinTD paired RD 3 correctly and the switch would have caused less problems in rd 4 to equalize. Board # 3 game has been played so that is done. Your suggestion would be to leave the pairings for the rest of rd 3 alone or change board # 1 from 1 vs 3 to 3 vs 1 so the pairings for rd 4 will equalize?

… We will finish playing rd 3 on the 26th, so would it be bad to repair 1 vs 3 to 3 vs 1 to correct the Equalization in rd 4.

Don’t do that. Leave it as 1 vs 3.

First, 3 needs black to equalize, 1 wants black only to alternate, so 3 should get black. Again, equalization should take precedence over alternation.

Second, you already have bad colors on 2 of the 4 boards in round 3. That’s enough bad colors to avoid the Small Tournament problems!

In general, in an 8-player tournament where all the colors worked in round 2, it is ideal to have 2 bad colors in round 3. You’ll probably find that round 4 won’t be much of a problem.

P.S. Pairing 4 vs 7 rather than 7 vs 4 does not change the fact that there are 2 bad colors in round 3. Any time two players are paired who are due the same color, that’s a “bad color”, regardless of which way the badness is resolved.

Thank you for the understanding. I have learned something.

Thanks all.
