Work in progress

Cat's Heart, is an opener made by Be_Crazy. It yields a T-Spin Mini (TSM) or a Skim Single, followed up by TSD and a Perfect Clear, or can be upgraded to a myriad of other T-Spin setups like Fractal, TST, STSD, etc, or even a C4W (!!!).

Indepedently created from MDF by benmuga, my goal was to find a Mini T-Spin opener with higher chances for 4-Line Perfect CLear (4L PC) with excellent versatility. If Cat's Heart interests you, do check out MDF <3.

Tips and tricks

· Some tips to memorize the opener easily are: Heart!

For those that is experienced with T-Spins, this shape is a staple in 6-3 and needs no introduction; it lends itself well to T-Spins indeed. This is why Cat's Heart is named as such — Cat refers to a PC solution with an extra scoring of T-Spin, like how cat gets through small spaces, and Heart is Heart <3.

... Or you can say Clear Allowing T-Spin if you prefers that more.

· Substituting TSM with ZSS, or Z-Spin Single

With the release of All-Minis attack table for Season 2 of TETR.IO Beta, this opener suddenly got a lot more versatile! The residue of the two boards afterwards are exactly the same, so see for yourself!
