Very nice mates by discovered check, given by the pièce of promotion.
Congratulations Menachem !
Clever forcing of the move order. In the first solution the wRe5 prevents 2.Se5??, then 4.Rg5 must wait until 3…Rg1-g7 has been played. Also 4…Qe5? 5.Rg1+ Rxg1+ 6.Sxe5! In the second solution 3.Rd2 allows 3…Bg8, and 4…Qb8? 5.Sb3+ Qxb3!
